in the hub and at the other end-in a elly 12, which in the construction herein shown be# comes an inner rim.

We valso employ an inner 13 adapted to t upon and abut against the telly 12.', Centrally the'outeri face off the rim'13 is recessed at 14 andthe inner rim 13 is flanged or extended as indicated at.; 15.-16. This inner rim 13 is alsoprcvided with cleats 17 -or 'other means by` which` through suitable bolts l18 the telly .and inner4 rlm are connected Aand secured together: .ln any manner known to thev art, .we sec-ure a pneumatic -tube :19 to the flange 15. o theinner 'rim 13, and similarly a/pneu-matic tube 20 is secured -tothe lflange ltofthe. inner rim 13. f Associated with the pneumaticytubes there's an outer rim which as shown-inthe drawing is made in. two partswindicated:atv Each Of-these parts is 'circularv and reoessed'to receive the outer. .portion of the pneumatic tubes. At its inner-edge the outer rim member 21 is flanged asindifcated at 23 and similarlyt at its inner edge, the outer rim 'member 22 is'flanged as indi-' cated at 24'.. Thetlangedpartsf23 and-21=` of the` outerrimv members are: adapted to; overlap and contactl with each. other. llying between the adjacent sides of. thecpneumatic; tubes 19 and 20,1and' 'these flanged part/soi the outerrim rmember may be conveniently. secured together by means of screwsy 125 or otherwise.
